About PDR Network

PDR Network combines the Health Care Notification Network (HCNN) and the Physicians' Desk Reference (PDR) to provide prescribers with a complete, end-to-end service. The PDR is the leading provider of print and online pharmaceutical information to physicians, and the HCNN is the only FDA-compliant network that electronically delivers specialty-specific product safety notices to prescribers. Improving patient safety and reducing physician liability requires prompt, expert delivery of important patient-safety information: PDR Network (formerly Medem) is ideally suited to fulfill this need.
